Stable isotope ratios of Antarctic echinoids from the PS81 - ANTXXIX/3 Polarstern expedition

This dataset contains carbon and nitrogen stable isotope composition of 120 Antarctic sea urchins belonging to 10 taxa (Abatus cavernosus, Amphipneustes rostratus, Amphipneustes similis, Aporocidaris eltaniana, Brachyternaster chesheri, Ctenocidaris gigantea, Notocidaris gaussiensis, Notocidaris mortenseni, Sterechinus antarcticus and Sterechinus neumayeri) and sampled in Drake Passage, Bransfield Strait and Weddell Sea during the ANTXXIX/3 (PS81) cruise of RV Polarstern in 2013. This data supports the article "Trophic Plasticity of Antarctic echinoids under contrasted environmental conditions" by L.N. Michel, B. David, P. Dubois, G. Lepoint & C. De Ridder, published in Polar Biology (doi: 10.1007/s00300-015-1873-y). Please refer to the article or contact Loïc Michel (loicmichel[at]gmail.com) for details.
